Question

a bus travels 4 km due north and 3 km due west going from bus station a to bus station b. the magnitude of the bus displacement from station a to station b is what km

Answer 1

5km

Step-by-step explanation:

Magnitude of displacement is found by getting the resultant. Resultant is same as the bypotenuse hence

`R=\sqrt {{x^(2)+y^(2)}` where x is the displacement in west direction and y is displacement in North direction. Substituting x with 3km and y with 4 km then

`R=\sqrt {{3^(2)+4^(2)}=5km`
